Is it normal i love someone this way

I am what I call somewhat into a guy I sort of havent met yet but I find strongly attractive. Even his words and pictures make me happy on any sad day. Ive listened to some songs that remind me of him now, and he seems to always beat the other guys at the end of day that I fantasise about and I want to love his imperfections. I want to get to know his scent and to adore his personality. and also I keep coming up with words I use for him. He seems to calm me down and does everything id want in a man. I just cant have him right now...which is even funnier because sometimes I wish his current girlfriend could love him "well" and make him happy. I often wonder about his previous girlfriends and feel like I have no chance so I just hope hes happy either with or without me. For as long as I can admire him from afar and hear from him time to time. I also have weird ways of behaving when anything related to him happens. for instant if anyone talks about something that reminds me of him I turn into a really girly flower feminine type of person and I start saying things like "oh, your hands are so manly and adorable" and "I would by you stuff and presents to see you smile for your eyes only"

he keeps on saying he has a girlfriend. the funniest thing is I had planned to be asexual for a long time since I came out. but I recently admitted I would do anything to be with him and id like him to "cure" me lol. Now I sort of think differently about sex. with anyone else I wouldnt. not even the men I fancy alot. just him. I dont know, it feels like I need to know him forever. I just wish I could hold him and become whimsical around him.

he seems like everything from looks to personality to what I dream of, except maybe all the arficual things like height and I guess if accent was to be one (yeah im very procice and difficult which is why I feel hes up there)

I also am holding back any other relations because everytime he replies me back, I cant help but fall inlove with him more.

thoughts?
